From Derech Emet
Yaarot Debash, Volume 1 of 2, Derush 1, page 2:
The seven days between Rosh HaShanah and Yom Kippur match the seven days of the week.
During every one of those seven days, you should repent for the sins that you committed. on the matching day of the week.
For example, during the first day after Rosh HaShanah,you should repent for the sins you committed on. the first day of the week [Sundays] throughout the year.
On the second day after Rosh HaShanah, you. should repent for the sins you committed throughout. the year on the second day of the week [Mondays].
This way, all of your days will be corrected.
